Posted on: 16.02.2026

Understanding PANalytical Laboratory XRF Technology

PANalytical represents industry leader in X-ray analytical solutions, providing wavelength dispersive and energy dispersive XRF systems trusted by thousands of laboratories worldwide. The laboratory systems employ sophisticated X-ray optics, advanced detection technology, and comprehensive sample handling automation delivering analytical performance supporting certification-quality results, regulatory compliance, and research publications requiring defensible data quality.

Laboratory XRF differs fundamentally from portable handheld analyzers through multiple critical dimensions. Stationary installation enables powerful excitation sources delivering superior sensitivity. Optimized measurement geometry minimizes variables improving precision and accuracy. Automated sample handling processes hundreds of samples with consistent conditions. Advanced detection systems achieve energy resolution enabling trace element detection impossible with handheld technology. Comprehensive software provides method development, quality control, and data management supporting quality system compliance.

The technology employs either energy dispersive (EDXRF) or wavelength dispersive (WDXRF) configurations. Energy dispersive systems measure fluorescent X-ray energies directly through solid-state detectors enabling simultaneous multi-element analysis. Wavelength dispersive systems employ crystal diffraction separating X-rays by wavelength enabling superior energy resolution and detection limits. Professional laboratories often employ both technologies strategically—energy dispersive for rapid multi-element screening, wavelength dispersive for demanding applications requiring ultimate precision.
